      The Armbian “distro” is a build framework to create ready-to-use images with working kernels in variable user space configurations for supported single board computers (SBCs). These are usually Debian or Ubuntu flavored.

      The term “Armbian” is comprised of ARM for the RISC processor architecture and the last half (bian) from Debian. Unlike Debian, Armbian Linux is focused and optimized for the ARM architecture. This can be a handy alternative to those who play in the realm of alternatives to the Raspberry Pi board.

    • ZDNetA new Chromebook saved my bacon when my old one died mid-business trip

      So, there I was in Austin, Texas, covering The Linux Foundation's Open Source Summit a few weeks ago when -- pop! -- an electrical surge blew out my Lenovo IdeaPad Duet 5, a great two-in-one Chromebook/tablet.

      Argh!

      I was on deadline -- when am I not? -- but I didn't have a backup machine with me. I was in deep trouble. But I was already ready for this disaster. Indeed, one of the reasons I've been a Chromebook fan since they first rolled out of the factory is that if a Chromebook dies on you, you can replace it and be back in business in no time flat.

          To test KDE Plasma 5.25, I installed a new virtual machine using the KDE Neon distribution. At first, I attempted to use the testing release, but that failed every time I ran the installer.

          Instead, I opted to go the stable route, which offers a lovely presentation of what KDE Plasma 5.25 is all about. I will warn you even the stable version of KDE Neon (as shipped with KDE 5.25) isn’t exactly the most stable desktop I’ve ever tried. In fact, I found KWin regularly crashed on me. Is this a product of Neon or KDE 5.25? We may never know. It took me a few installs, but I eventually managed to get a reliable desktop up and running.

      • Enterprisers ProjectIT careers: 3 hot automation jobs right now

        IT execs and hiring managers aren’t just prioritizing automation skills anymore. They’re carving out whole roles that are largely defined by IT automation.

        This is a twist on the general fear that automation eliminates jobs. It’s true that automation – not just in IT but across a wide range of roles and industries – is impacting various jobs, now and in the future. But automation will also likely create many new jobs that don’t exist yet or didn’t exist, say, 10 years ago, even as it gets rid of other positions.

        IT occupies an interesting space in that broader trend. Many of the dominant and emerging trends in IT – hybrid cloud, containerization, orchestration, CI/CD, cybersecurity – depend heavily on automation. That means they also depend heavily on people with the right mix of skills to implement and manage the various tools and technologies underpinning modern software development and IT infrastructure.

          Pip is the most popular and versatile package installer for Python. It offers a command-line utility that allows you to manage Python packages easily. Using pip, you can perform actions such as downloading, installing, updating, and uninstalling packages with simple commands.

          Pip uses a caching mechanism that allows you to download and install Python packages faster. It works by storing a cache of the downloaded packages on the local wheel.

          The caching mechanism allows pip to improve the download and installation of the packages. This is because pip does not need to download already existing packages.

          In some cases, pip may not need to redownload a package when updating if it already exists in the cache.

          This tutorial will discuss how to work with the pip cache, how to manage the pip cache using various commands, and how to clear it when you need to start afresh.

Stick with us if you want—we promise that’s the last sticker pun you’re going to read here.

      • EFB Tampering. Holdover Time | Pen Test Partners

        A quick search online for EFB applications shows plenty of third party software available to use on EFBs. Many of these applications are available for download on public app stores. Some of these applications are developed by small software companies, others by large well known software developers. It is not for us to speculate how much involvement or oversight state regulators have had in the development and testing of these EFB applications, but we should keep in mind that there are thousands of EFB applications available and they can originate from anywhere in the world.

        With regards to EFB integrity, often the complication with third party applications, as opposed to performance applications, is the added risk of using different data sources as well as the potential for using software which has not been risk-assessed or security tested to the same standard as that of aircraft manufacturers. Performance applications will complete calculations locally and any required data is entered by the pilot. Many third party applications complete calculations locally but require access to databases online to source required information. In some cases, these databases are connected to other databases which feed into them. This creates more attack surfaces for tampering with an EFB.

        • Internet Freedom FoundationCIC directs Delhi Police to respond afresh to IFF's RTIs seeking information on use of FRT in policing

          In 2020 and 2021, we filed three RTI applications with the Delhi Police seeking information on their use of FRT. The information was refused under Section 8 of the RTI Act. Some information was refused on the ground that it is not available. The Delhi Police also said they have “Nil” information on CCTV cameras! Our first appeals against these responses were rejected, so we filed Second Appeals with the Central Information Commission. They were heard on June 29, 2022, and the Delhi Police were directed to revise their response to the RTI applications, in compliance with the RTI Act.

          [...]

          IFF has been tracking the development of the Delhi Police’s facial recognition system since 2019, along with tracking instances of facial recognition use in the country overall, through Project Panoptic. In October 2020, we filed two RTI applications with the Delhi Police, seeking information on their use of FRT in traffic management and criminal investigation, which was widely reported in the media. In 2021, media reports also recorded the Delhi Police’s use of FRT for investigations in the pogrom that took place in North-East Delhi in February 2021. So, we filed another RTI application with the Delhi Police in March 2021 asking them for information on this.

        • Could fake news provoke violence in Kenya’s elections?

          Daily life, for better or worse, revolves around having access to the internet, and the Kenyan government wants to assure its citizens that that will not change during the upcoming general election cycle. Kenya’s general elections to elect a new President and members of the National Assembly will take place on August 9 and the race is close and tense. Much of the tension is the result of the outgoing president, Uhuru Kenyatta, throwing his support behind opposition leader Raila Odinga rather than William Ruto, the current deputy president.

          Waves of disinformation pushed by paid social media influencers have been a growing concern in the run-up to elections that some experts worry could lead to violent eruptions. The country is still haunted by clashes during the 2007 elections that left over 1,000 people dead and hundreds of thousands displaced. Kenya’s National Cohesion and Integration Commission (NCIC), set up in the wake of the violence 15 years ago, rates the likelihood of electoral violence as just about “medium high risk,” while in Nairobi County, home to the capital city, the risk of violence is considered to be “very high.”

      • AccessNowThe Digital Services Act: your guide to the EU’s new content moderation rules - Access Now

        After three years of intense negotiations, the EU Digital Services Act has finally arrived. On 5 July 2022, the European Parliament approved the final text of the future EU content moderation rule book. The DSA has been labeled by some as a “gold standard” for content and platform governance in the EU. In this blog post, we unpack what this long-awaited law contains and what changes people can expect to see as the law becomes applicable in 2024.

        [...]

        The DSA applies to hosting services, marketplaces, and online platforms that offer services in the EU. The DSA will apply to all providers regardless of their place of establishment. In other words, if individuals are residing in the EU they will fully benefit from the DSA’s protective scope. Hence, the DSA is putting people first by default and not corporate interests.

        New sets of obligations are designed as “made to measure”: the DSA singles out Very Large Online Platforms (VLOPs) as well as Very Large Online Search Engines (VLOSEs), which are platforms with more than 45 million average monthly active users in the EU. This way, the law rightly recognises the platforms’ specific control over public discourse and the often manipulative influence they have on people’s behaviour online.

      • Irish TimesCalls for investigation after deadly crackdown on Sudanese protests

        Internet shut down for 20 hours during demonstrations when tens of thousands took to the streets

        Demonstrations have been continuing in Sudan as citizens demand an end to military rule, with the death toll rising to at least 113 protesters killed since the military coup last October.

        Last Thursday, the internet was shut down for about 20 hours during protests when tens of thousands of civilians took to the streets of the Sudanese capital Khartoum and its twin cities of Omdurman and Bahri; at least nine people were killed. Participants and Sudanese activists abroad had been sharing photographs and videos of the demonstrations on social media using the hashtag #EyesOnSudan.

        “It is unacceptable for the military in Sudan to continue to perpetrate brutalities against the Sudanese people during protests whenever the internet is shut down. This impunity must be condemned by all,” tweeted Felicia Anthonio, a campaigner who works with Access Now on their #KeepItOn campaign, which fights against internet shutdowns.

      • AccessNowThe Indian government’s overbroad Twitter takedown orders must be declared unconstitutional - Access Now

        Online freedom in India is in peril — constitutional courts must intervene and protect the rights of millions.

        Twitter’s legal challenge against the Indian government’s blocking orders comes against the backdrop of rising digital authoritarianism, and imminent threats to free speech. The court must declare the government’s overbroad censorship actions as unconstitutional, and bring to light authorities’ abuse of power online.

        The Indian government and Twitter have locked horns in the past, but this case is not about one Big Tech firm versus the Indian government. It is about protecting human rights, and holding the Indian Ministry for Electronics and Information Technology to account for abusing its already flawed web censorship powers under India’s Information Technology Act.

        “A democracy cannot survive without free expression, and the current wave of digital authoritarianism in India puts the world’s largest democracy at risk,” said Raman Jit Singh Chima, Senior International Counsel and Asia Pacific Policy Director at Access Now. “Authorities are targeting people for content posted online, and regularly intimidating web platforms and social media services into complying with its censorship through rights-violative tools such as the IT Rules and other provisions of the Information Technology Act. Today, Twitter is standing up for the population and doing what should be the government’s job: safeguarding our rights.”

      • Writing for the sake of writing

        I've recently pruned many of my old posts, after doing a quality check. Some were something that wasn't worth-reading, not leaving you with a sense of "oh! didn't know that! awesome that I learnt something new about X", something which I strive to achieve from now on, on my new posts. Of course, I can't always achieve that, so there'll be some ramblings here and there.

        I wrote many of the posts just for the sake of writing that day, not that I felt inspired or the need to write that day, which as I later realised it's the wrong mentality for a blog. From now on, the blog will be more of a self-reflection journal and memory bank, things that help me over all. I'm happy that someone else can take and be influenced by an idea I put on the table. Even if the post inspired one reader, it's a great thing.

      • My inability to write well

        As for myself, I teethgnashingly write more "I think", "for me", "it seems to me" and so on, on my own blog no less, because I kept getting pushback from people commenting on my blog arguing with me that the things I said are not universally true, which seems super obvious to me because I am writing on my blog. Grrrrr.

        Perhaps I hear my words in my own voice, see myself sitting in a coffee house with friends, and we don't qualify every statement. Those qualifications are implied by the simple fact that we are people talking to each other.

        Other people are probably hearing those words like they read the newspaper. "News" is supposedly "universally true" or aims to be. I think. Hah!

      • I am forced to use Google

        It seems to me that I have been force-fed Google's services by almost everyone in my life: friends, family, but most notably school. My school's tech department *really* loves Google and uses it for *everything* - Google Classroom for homework assignments, Gmail for all communications, Google Slides for lesson presentations, I could go on all day. What really bugs me is the fact that in order to see what homework I have, I have to log in to Google Classroom every day, using an account with my real name on it! As if just using their products wasn't enough, they made a G Suite for Education account for every student with no warning or prior notice, using real names! (Granted, when I joined in year 7, I was fairly indifferent towards Google, but still.)
